Cooperative Diversity in Wireless Networks: A Geometry-inclusive Analysis
نویسندگان
چکیده
Cooperation between physically separated wireless nodes can achieve the high signalto-noise ratio (SNR) diversity gains characteristic of multi-antenna arrays. Simulations indicate that such gains are still achieved for SNRs in the range of practical interest for several applications. Cooperation further yields SNR gains in addition to diversity gains. In contrast to diversity, the SNR gains are affected by the choice of inter-node distances. Such SNR gains are quantified in this paper via a geometry-inclusive error analysis. The notion of geometry-inclusive SNR gains is developed to facilitate geometry-based comparisons of cooperative strategies.

Performance Analysis of Wireless Cooperative Networks with Iterative Incremental Relay Selection
In this paper, an iterative incremental relay selection (IIRS) scheme is considered for wireless cooperative networks in order to increase the reliability of transmission. Different from the conventional incremental relay selection which incrementally selects a best relay for only one iteration; the IIRS scheme iteratively applies the incremental relaying and relay selection processes. To evalu...
متن کاملA Novel Protocol for Cooperative Diversity in Wireless Networks
Recently, cooperative diversity has emerged as a means of providing gains from spatial diversity to devices with single antennas. Yet, the performance of these protocols remains limited in symmetric networks. In this paper, we investigate the performance of a novel “detached” cooperative diversity protocol that is designed for asymmetric networks, both in terms of outage probability and frame e...
متن کاملCooperative multi-hop transmission in wireless networks
We consider various relaying strategies for wireless networks by comparatively examining direct transmission, conventional relaying, and the novel concepts of cooperative relaying. The latter build on two inherent benefits of relaying systems: the spatial diversity offered by the relay channel, and the ability to exploit the broadcast nature of the wireless medium. Studied cooperative protocols...

Cognitive Radio (CR) networks enable dynamic spectrum access and can significantly improve spectral efficiency. Cooperative Spectrum Sensing (CSS) exploits the spatial diversity between CR users to increase sensing accuracy. However, in a realistic scenario, the trustworthy of CSS is vulnerable to Spectrum Sensing Data Falsification (SSDF) attack. In an SSDF attack, some malicious CR users deli...

This paper studied the problem of the throughput of multi-hop multi-relay wireless sensor networks based on the cooperative diversity technology. At first, the paper established the cooperative diversity model for multi-source, multi-sink and multi-relay sensor networks, on which the specific expression of throughput of wireless sensor networks was deduced, it not only prove that the throughput...
